Scrum PSM-I - Professional Scrum Master I

When many Development Teams are working on a single product, the definition of “Done” must be shared by all Development Teams and make their combined work potentially releasable, as stated in [4]: “When multiple teams wo rk together on one product they must mutually define and comply with the same Definition of Done. This makes sure all Increments adhere to a consistent quality level.”

According to the Scrum Guide 1 , ordering Product Backlog items is solely up to the Product Owner’s discretion. The Product Owner orders items in the Product Backlog to best achieve goals and missions. To do this, they optimize value by considering various factors such as cost and benefit, risk, dependencies, date needed, etc. The Product Owner is responsible for maximizing the value of the work the Development Team does.

The best two answers are A and C. These two ways of creating Scrum Teams are consistent with Scrum’s values because they respect the self-organization and empowerment of the people who will be working in the teams. They also foster openness and courage by allowing the people to express their preferences and opinions about the new structure.

B, D and E are not consistent with Scrum’s values because they impose a top-down approach that does not involve the people who will be affected by the change. They also undermine the commitment and focus of the teams by assigning them to work on something they may not be interested in or passionate about.

Scrum is a framework for developing, delivering, and sustaining complex products. Scrum has three roles: the Product Owner, the Scrum Master, and the Developers. The Developers are the people in the Scrum Team who are committed to creating any aspect of a usable Increment in each Sprint. The Developers are not limited by titles such as programmer, designer, tester, architect, engineer, etc. The Developers are responsible for all aspects of quality, including finding and fixing bugs, tracking quality metrics, and verifying the work of other Developers. Therefore, Scrum has no “tester” role, and the Developers are responsible for quality.

The correct answer is B, because multiple Scrum Teams working on the same project do not have to have the same Sprint start date. The Scrum Guide states that “multiple Scrum Teams often work together on the same product. One product goal unites them. Therefore, they must mutually define and comply with a definition of ‘Done’ that applies to their combined work product.” Therefore, the synchronization of multiple Scrum Teams is based on their shared product goal and definition of ‘Done’, not on their Sprint start date.

According to the Scrum Guide, the Developers do the work to make sure Product Backlog items conform to the Definition of Done, as they are responsible for creating a “Done” Increment that meets the Definition of Done. The other options are not valid, as they imply that the work is done by someone else outside the Development Team (such as Quality Assurance Team) or by another role on the Scrum Team (such as Product Owner or Scrum Master).

A Sprint may be cancelled only if the Sprint Goal becomes obsolete. This makes Option A the correct answer. The Scrum Guide is very clear that only the Product Owner has the authority to cancel a Sprint, although that decision may be influenced by stakeholders, the Developers, or the Scrum Master. The reason for cancellation is not general disruption, poor forecasting, or the appearance of new work. It is specifically tied to the Sprint Goal no longer having value or relevance.

Option B is incorrect because a new business opportunity does not automatically justify cancelling a Sprint. Scrum is designed to handle change without disrupting the Sprint unless the Sprint Goal itself is no longer valid. Option C is incorrect because feasibility concerns should be addressed through collaboration and adaptation, but they do not by themselves define the cancellation rule. Option D is incorrect because not finishing all selected work is not a reason to cancel a Sprint. Scrum accepts uncertainty, and the team inspects and adapts. The Sprint Goal remains the key commitment, and as long as it is still relevant, the Sprint should continue.

The Development Team must do as much work as it has told the Product Owner will be done for every Product Backlog item it selects in conformance with the definition of “Done”, as stated in the Scrum Guide 1 : “The Development Team works to forecast the functionality that will be developed during the Sprint. The Product Owner discusses the objective that the Sprint should achieve and the Product Backlog items that, if completed in the Sprint, would achieve the Sprint Goal. The entire Scrum Team collaborates on understanding the work of the Sprint.”

The correct answers are A and D, because these ways of creating Development Teams are consistent with Scrum’s values. Allowing existing teams to propose how they would like to organize into the new structure respects their self-organization and empowerment. Bringing all the developers together and letting them self-organize into Development Teams also respects their autonomy and collaboration.

According to the Scrum Guide 1 , when multiple Scrum Teams are working together on one product, they must coordinate their work with each other. One way to do this is through Nexus, a framework for scaling Scrum. Nexus helps to reduce cross-team dependencies and integration issues by making them more transparent. Multiple Scrum Teams working on one product use one Product Backlog.
